Using the tenary operator in C with 3 numbers

[Kernelpanic]

The tenary operator was discussed here for some time ago, a bit complicated in Basic. It is quite useful for simple comparisons.

The program uses the tenary operator in C with a triple comparison. It also works with four numbers, but that gets a bit confusing. If one only want to compare two numbers, simply enter 0 for the third number. -- Both files in the same directory.
